Warning: This build is Socket Heavy and was made for Campaign / Early map progression, anything that is beyond that is left for your discovery. I am neither the best player, neither it's best option for Wintertide Brand Cold DoT,
it's more of how i would do so if i had a task to complete Campaign, have done all 3 Labyrinths and be prepared for early mapping on Wintertide Brand on Fresh account/League Start under 4h. Enjoy!
